Typically Text on Top is used to provide captions on top of the presentation. However, this "Vision" App allows an individual (visual impaired) user in the audience to receive the real-time text using a Text on Top micro dongle.
The user is in full control to adjust the appearance to his/her specific needs.
A Text on Top micro dongle is a USB hardware device. This means your tablet must support "USB host mode" in order to work. Most tablets and phones support this operation mode, but if you are about to purchase a tablet to work with Text on Top, make sure it meet this requirement!
